DTC646, PWM Fan Speed Controller
The TC646 is a switch mode, fan speed controller for use with brushless DC fans.
Temperature proportional speed control is accomplished using pulse width modulation (PWM).
A thermistor (or other voltage output temperature sensor) connected to the VIN input furnishes the required control voltage of 1
